Meet Kim You-jung’s Parents: Mok Seon-mi and Kim Sang-pae

Kim You-jung, celebrated as “Korea’s Little Sister” and widely regarded as a “sageuk fairy” for her standout performances in historical dramas, has been a prominent figure in South Korean entertainment since early childhood.

Born on September 22, 1999, in Seongdong District, Seoul, she is the youngest of three children, with an older brother, Kim Boo-geun, and an older sister, Kim Yeon-jung, who also pursued acting.

Her parents, Kim Sang-pae and Mok Seon-mi, have remained largely outside the spotlight, offering steady support throughout her career.

Kim entered the industry at just four years old after her mother shared her baby photos online, quickly earning modeling roles and progressing into acting.

Her charm and mature performances made her one of the country’s most beloved child stars, earning her the title “Nation’s Little Sister.” She later attended Goyang High School of Arts, graduating in 2018, and opted to prioritize her acting career rather than enrolling in a university program.

Kim You-jung is 26 years old. She is of Korean nationality and ethnicity and practices Protestant Christianity. Standing approximately 160–164 cm tall (around 5’3″), she remains unmarried with no children and keeps her personal life highly private.

Despite occasional dating speculation linked to co-stars, no romantic relationships have ever been publicly confirmed.

Today, Kim is recognized as one of South Korea’s leading actresses, having successfully transitioned from child star to an acclaimed adult performer while maintaining a wholesome, admired public image.

Mok Seon-mi

Mok Seon-mi, born in 1968, is the mother of Kim You-jung and played a pivotal role in launching her daughter’s entertainment career. It was Mok Seon-mi who uploaded photos of baby You-jung online, catching the attention of advertisers and leading to her first commercial gig at a young age.

This serendipitous act propelled You-jung into the spotlight, where she quickly became one of Korea’s most sought-after child actresses. Described as a steadfast supporter, Mok Seon-mi has been by her daughter’s side through the challenges of child stardom, offering guidance and encouragement.

Kim You-jung has publicly expressed gratitude toward her mother for helping her navigate fame responsibly and “growing up well.” The family values privacy, and Mok Seon-mi has maintained a low profile, focusing on behind-the-scenes support rather than public appearances.

Kim Sang-pae

Kim Sang-pae, born in 1961, is Kim You-jung‘s father and the head of a family committed to avoiding media attention. He and the family have intentionally kept details private to shield themselves from the spotlight that follows their famous daughter.

As the father of three children—including You-jung, an older son (born 1993), and an older daughter, Kim Yeon-jung (born 1996, who also became an actress—Kim Sang-pae has contributed to a grounded upbringing in Seoul.

His role emphasizes the family’s preference for normalcy amid You-jung’s high-profile career, providing a stable foundation that has allowed her to thrive in the industry. Kim You-jung‘s success is often attributed to her talent and hard work, but the supportive, low-key environment created by her parents has undoubtedly played a key part.

While Mok Seon-mi‘s entry into acting sparked her career, both parents have helped her maintain balance and humility amid stardom.
